(PhD Thesis;2010:10, Doctoral thesis, 2010)Enterococcus faecalis is commonly found in the gastrointestinal tract of humans. It is also an opportunistic pathogen and one of the leading causes of nosocomial infections worldwide. The treatment of E. faecalis infections ... -
Antifungal activity of chitosan/chitooligosaccharides alone and in combination with chemical fungicides against fungal pathogens
(PhD Thesis;2013:12, Doctoral thesis, 2013)Botrytis cinerea Pers. ex Fr. is an economically important pathogen causing gray mold in over 200 plants species worldwide, including strawberry (Fragaria × ananassa). In Norway, gray mold is economically the most important ... -
Application of Bayesian calibration for propagation of uncertainty in dynamic models
(PhD Thesis;2010:8, Doctoral thesis, 2010)The thesis is about quantification of uncertainties in complex models. Models are built to describe, explain or predict a real world outcome. It is well known that models are related with uncertainty, and that uncertainties ... -
Applied and fundamental perspectives on brown-rot decay mechanisms
(PhD Thesis;2019:14, Doctoral thesis, 2019)Woody biomass is an important material for the growing bioeconomy, and has gained significant attention as a feedstock for second-generation biorefineries. Wood has traditionally been used as a building material for ... -
Better understanding of the relation of the dynamic sensory perception of solid and semi solid foods with consumers’ preferences and their perception of satiety
(PhD Thesis;2019:5, Doctoral thesis, 2019)Nowadays, overweight and obesity has been recognized as one of the main reasons that leads to many non-communicable diseases such as diabetes, high blood pressure, cardiovascular disease and in some cases cancer. Therefore, ... -
Biochemical investigation of catalysis by lytic polysaccharide monooxygenases
(PhD Thesis;2016:69, Doctoral thesis, 2018-05-04)Lytic polysaccharide monooxygenases (LPMOs) are copper-dependent enzymes that catalyze the oxidative cleavage of glycosidic bonds in the presence of dioxygen and an external electron donor. Currently, these enzymes are ... -
Bruk av laktase og standardisert melk til produksjon av Cottage Cheese
(Master thesis, 2015-07-01)Norwegian: Oppgaven omhandler småskalaproduksjon av Cottage Cheese ved bruk av laktase og standardisert melk. Det ble undersøkt effekt av 3 forsøksfaktorer på sammensetning og kvalitet til Cottage Cheese. Målet var å oppnå ... -
Cell-shape regulation in Streptococcus pneumoniae : EloR/KhpA, a new regulatory pathway administering cellelongation
(PhD Thesis;2020:36, Doctoral thesis, 2020)The oval shaped Streptococcus pneumoniae utilizes both septal and peripheral peptidoglycan (PG) synthesis in order to maintain its shape. The protein complexes responsible for synthesizing PG are called the elongasome and ... -
Characterization of fecal lactic acid bacteria isolated from healthy Ethiopian infants : bacteriocin production and antibiotic suscepebility
(PhD Thesis;2011:55, Doctoral thesis, 2011)In this thesis lactic acid bacteria (LAB) were isolated from fecal samples of healthy Ethiopian infants, identified to species level, screened for bacteriocin production and tested for antibiotic susceptibility. Enterococci ... -
Characterization of the infant gut microbiota mobilome
(PhD thesis;2017:37, Doctoral thesis, 2017)The human gut is densely populated with a wide diversity of bacteria. These bacteria can serve as a reservoirs for multiple Antibiotic Resistance (AR) genes that in turn are associated with wide range of Mobile Genetic ... -
